How to activate ACPI 2

[jisoo22]

Hello all,

I'm running the new Fedora (aka RedHat 9). I discovered that ACPI is off by default, hence I always have to push the power button to completely turn off the computer at shut down. My understanding is that if ACPI is on, then the computer will turn itself off on shut down. If this is right, does anyone know how to activate ACPI? I've looked around and found places that say I should turn it on but do not tell me how.

Thanks,
Jisoo22

I think you need to compile ACPI support into your kernel.

Yes its a specific main menu item when you compile the kernel.

Hello Jisoo22,

I had this same issue under Redhat9 when I recently upgraded my mobo.

You add a command onto the kernel boot line and it starts working fine. Problem is that I cannot remember what that line is. I will endeavour to check this and post a reply tonight from home for you.

apm=power_off

That's the bit you need to add to the kernel boot parameters. Once you've started off that, a shutdown should actually power the machine off.

Curious to see if wmg's advice works. If not, try this link out:

http://fedora.artoo.net/forum/viewtopic.php?t=101&highlight=acpi

It says to add an "acpi=on" to the boot command. Modify your /boot/grub/grub.conf file and add that to the appropriate line to make it happen at each boot automagically.

The FAQ area at

http://fedora.artoo.net

is really good for Fedora users. I also get good signal-to-noise when in #fedora on irc.freenode.net.
